DISH-WASHER.

No. 902,064. Specification of Letters Patent. 7

Application filed November 25, 1907. Serial No. 403,784.

To all whom it may concern: I

Be it known that I, CHARLES W. FETHER- OLF, a citizenofthe United States, residing at Binghamton, in the county of Broome and State of New York, have invented'a new and useful Dish-Washer, of which the follow- This invention relates to dish washers and has for its object to provide a strong, durable and thoroughly efficient device, of this chare acter particularly designed for use in hotels, boardlng houses, restaurants and similar places and by means of which several pans or tra s of dishes may be thoroughly washed at eac operation of the machine.

A further object of the invention is to provide a dish washer including a liquid containing tank having a rock shaft j ournaled therein and provided with oppositely disposed arms for supporting the tray or trays of dishes to be washed, said trays being altercontaining receptacle whenthe rock sha t is operated.

A further object is to provide an o crating lever having one end thereof pivota 1y connected with the rock shaft and provided with spaced ears or lugs adapted to engage the, supporting frame when the handle is moved to inoperative position thereby to lock the shaft against rocking movement.

A further object is .to provide improved means for supplying water to the liquid con-' taining tank, andmeans for discharging the same after each washing 0 eration.

A still further object o the invention is generally to improve this class of devices so efficiency. I

Further ob ects and advantages will appear in the following description, it being understood that various changes in ,form, pro

may be resorted to within the scope of the ap ended claims.

The improved dish washer forming, the sub'ect matter of the present invention in-.

pipe and Patented Oct. 27, 1908.

clu es a substantially rectangular supporting frame 5 preferably formed of anglev iron, as shown, and provided with dependinglegs or feet 7 and oppositel disposed uprights or standards 8 and 9. l esting on the support-. ing frame and interposed between the uprights or standards 8 and 9 is a tank or rece tacle 10 having a transverse partition 11 d fining independent liquid containing compartments 12. The upper edge of the tank 10 is provided with a marginal reinforcing rim 1.3 which also serves to'defiect the water downwardly Within the liquid receiving compartments and thus prevent the Water from splashin over the sides of the. tank when the mac ine is in operation. The reinforcing rim 13 is provided with oppositely disposed openings 15 for the reception'of the adjacent uprights or standards 8 and 9, the metal constituting the rim bein wardly around said openin s to orm vertical reinforcing flanges 16. he upper or free end of the standard 8 is provided with a bearing 17 in which is journaled one end of a rock shaft 18 the opposite end of which is j ournaled in the bifurcated end 19 of the up.- right or standard 9. I The rock shaft 18 is.

preferably dis osed above. and in vertical alinement wit the transverse partition 11 and extending laterally from the rock shaft are oppositely disposed arms 20 provided with terminal hooks 21 which engage theadjacent hangers 22 of the dish receivin vessels 23for supportingsaid vessels within the adjacent liquid receivin com artments of the tank. One end of t e roc shaft 18 is provided with a vertically disposed boss 24, on' which is pivotally mounted at 25 anoperating lever 26, the latter being) 1provided with a terminal handle 27 prefera y disposed at right angles to the longitudinal axis of the lever 26, as shown. d

The pivoted end of the operating lever 18 is bifurcated to form spaced ears 28 which extend beyondthe pivot point 25 for engagement with the terminal lug 29 of the upright or standard8 when the operating lever is swun downwardly to, inoperative position paralllal with the rock shaft thereby to "lock bent up- I I spaced branch pipes which discharge into e liquid receiving compartments 12 through suitable inlet orts 31, said branch pipes being operative y connected with a pipe 32 whichlatter extendsto a suitable source of liqluid supply. A globe valve 33 is preferab y disposed between each branch pipe and the main ipe for controlling the flow of water from t e main pipe into the liquid receiving compartments.

Extending through the bottom of each liquid receiving compartment 12 is a i e section or socket 34 having its lower endhjhreaded for connection with a waste pipe 35, there being a clamping nut 36 threaded on the pi e section or socket 34 and bearing against the lower wall of the tank for clamping the latter in engagement with the lateral flange'37 of the socket member, as best shown in Fig. 5 of the drawings.

Arranged within each compartment is an over-flow pipe 38 having its lower end in clinedor beveled to form a plug 39 adapted to enter the adjacent socket 34, the opposite ends of said over-flow pipes being provided with suitable screens 40 through which the liquid in the compartment enters the overflow pipe when the liquid has reached a predetermined height.

In operation the over-flow pipes 38 are inserted in the socket member v 37 and the valves 33 moved to open position thus permitting the water to enter the compartments 12 through the inlet orts 31. The lever 18 is then swung'upwar ly on its pivotal axis 25 to vertical osition which disengages the terminals of t e ears 28 from the lug 29 thus permitting the lever to be oscillated to rock 'the shaft 18 and raise and lower the dish con.- taining vessels within the liquid receiving compartments. After the washing operation is completed the lever 18 is swung downwardly arallel with the rock shaft 18 which causes t e ears 28 to engage the lug 29 and in which position the shaft 18 will be locked against rocking movement. The plug 39 is then withdrawn from the socket 37 by exerting an upward movement or pull on the pipe. 38 which permits the water in the compartments 12 to be discharged through the socket member to the wastepipe 35.

' Any suitable device may be employed for heating the water inthe compartments 12 and in some cases the Water may be heated at a distant point and discharged into the compartments.12 in a heated condition.

From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled inthe art and further description thereof is deemed unnecessary. Having thus described the invention what is claimed is:

1. A dish washer including a supporting frame, a tank having a plurality of liquid receiving compartments, a rock shaft provided with oppositely disposed arms for sup orting a dish containing vessel within each compartment, and an operating lever ivotally mounted on the shaft for rocking t e latter thereby to alternately raise and lower the dish containing vessels, said operating lever being movable into engagement with the frame for locking the shaft against rocking movement.

2.

6. A dish washing machine including a supporting frame having spaced u rights, a tan mountedon the supporting f fame and provided with a transverse partitiondefining 1qu1d receiving compartments, a rock shaft ournaled in the uprights above the tank and rovided with oppositely disposed arms proecting within the compartments and providedwith terminal hooks for engagement with a dish containing vessel, and an operating lever pivotally mounted on the rock shaft and adapted to engage the adjacent upright for locking the shaft against rocking movement when the lever is moved to inoperative position. it

7. A dish Washer including a supporting frame provided with spaced uprights, a tank supported on the frame and provided with a marginal reinforcing rim having openings formed therein for the reception of the adjacent ends of the uprights, said tank being provided with a pluralityof liquid receiving compartments, a rock shaft journaled in the uprights and provided with means for supporting a dish receiving vessel, a lever pivotally connected with the rock shaft for 0 erating the latter, said lever being provlded with spaced ears adapted to engage the adj acent upright for locking said shaft against rocking movement when the lever is moved to inoperative position.

. In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
